Case Type   : 系统内部使用工具
Case Name   : 单节点关闭数据库后gs_ctl start -M在备节点指定pending启动
Create At   : 2021/01/18
Owner       : opentestcase015
Description :
    1.关闭正在运行的备机
    2.指定-M设置值为pending启动备机
    3.查看备机状态pending模式是否启动正常
    4.恢复备节点
    5.恢复环境
Expect      :
    1.关闭正在运行的备机成功
    2.指定-M设置值为pending启动备机成功
    3.查看备机状态pending模式启动正常
    4.成功
    5.成功
